United States Patent Office 3,150,049 Patented Sept. 22, 1964 3,150,049 BATH 01L Martin F. Emory, 1 Gracie Terrace, New York, NY. Filed Sept. 22, 1959, Ser. No. 841,601 16 Claims. (Cl. 167-90) This invention relates to bath oils and it has particular relation to homogeneous compositions which contain a perfume oil and are adapted to be used as bath oils.

The main object of the present invention is to provide a bath oil composition for use in bathing water, which contains pine oil or any other perfume oil of any desired fragrance in homogeneous colloidal distribution, is clear and stable on storage and, when added to water, is evenly and substantially dispersed to very fine particles capable of being taken up by wet human skin. Moreover, the product leaves a very thin, substantially uniform layer of oil on the surface of the human skin, when added to, and used in the bath. Said uniform layer of oil that is left on the skin, is acquired all over the body at one time by immersion and without massage.

Another object of the present invention is to provide a bath oil composition which contains ingredients benefical to the skin and which is absorbed and/ or absorbed from the bath Water by human skin and thereby smoothens and protects the skin and prevents a loss of moisture from the skin for a considerable period of time.

It is also an object of the present invention to provide a bath oil composition which, when added to the bathing water, leaves the human skin covered with a thin protective film of oil for long periods after the bath.

A further object of this invention is to provide bath oil preparations of the above described type distributed on a carrier therefor, said carrier consisting of fibrous material, e.g. fibrous tissues, towelettes, pads, and the like.

Further objects and the advantages of the invention will be apparent from the appended claims and the following specification which describe by way of example and without limitation some specific embodiments of, and some best ways of carrying out, the invention.

It has been found that a bath oil composition meeting all requirements, such as clearness, pleasant odor, absence of any irritating eifect, stability on storage and uniform colloidal dispersion in water to very fine particles which are quickly absorbed and/ or adsorbed by human skin, is obtained by proceeding as follows.

Pine oil, or another perfume oil having equivalent properties, and a suitable amount of lecithin are mixed under stirring with isopropyl palmitate and/or isopropyl myristate, and/or cosmetically applicable vegetable oil, and/or esters of other saturated or unsaturated monoor dicarboxylic acids having six carbon atoms or more, which are liquid and oily in character, are homogeneously miscible with the other ingredients of the composition, do not undergo polymerization and are cosmetically applicable, i.e., do not have irritating or other undesired effects, and/or mixtures of these substances, until a liquid product of uniform composition is formed which may or may not be filtered. This product is stable on storage and disperses to very fine particles of the above mentioned type, when brought in contact with excess water, e.g., poured into bathing Water. Into the liquid product consisting of pine oil, lecithin, and the ingredients described above, a neutral, stable non-irritating mineral oil product, e.g., the product known under the name liquid petrolaturn can be incorporated in order to bring it to the desired consistency and concentration.

Example 1 12.5 parts by weight of pine oil and 1.5 parts by weight of lecithin are mixed under stirring at a temperature of 60-80 C. with 50 parts by weight of isopropyl palmitate and 36 parts by weight of isopropyl myristate, to form a uniform mixture. To the latter 100 parts by weight of liquid petrolatum having at 60 F. a specific density of 0.830-0880 are added under stirring and the mixture is filtered, if necessary, in order to obtain a clear liquid.

Example 21 In the above examples, instead of liquid petrolatum other petroleum oils having equivalent properties (particularly miscibility, boiling range, lack of toxicity and absence of irritating effects) can be used preferably in substantially equal amounts. The liquid petrolatum as well as said other petroleum oils should preferably have a specific density in the range of 0.830 to 0.905.

Instead of petrolatum, or in mixture with the same, or in mixture with the above mentioned other petroleum oils, alcohol can likewise be incorporated in the compositions of the invention.

While the above examples illustrate the preparation of satisfactory bath oil compositions embodying the present invention, it will be understood that this invention is not limited to the steps, conditions, proportions and other details specifically described above and can be carried out with various modifications. For example, instead of the perfume oil-s described in the above examples, other perfume oils or compounded perfume oils (perfume oil compositions), for example, eucalyptus oil and petit-grain oil can also be used. The term perfume 'oil is used-throughout the present application to include also compounded perfume oils. The proportions of the individual ingredients may also vary. For example, in preparing a bath oil composition from (a) pine oil, ([1) lecithin, (c) isopropyl palmitate and (d) isopropyl myristate the proportions of these ingredients can vary within the following limitsa 7 Percent by weight said percent by weight being based on thetotal weight of the ingredients ((1), (b), (c) and (d). However, as illustrated by the above Examples 8 and 9, e.g., equal amounts of isopropyl palmitate and isopropyl myristate can be mutually substituted for each other in the composition of the invention. Furthermore, the isopropyl palmitate and/ or the isopropyl myristate, can be, partly or entirely, substituted by one or more vegetable oils, and/or one or more of the above mentioned esters of carboxylic acids, whereby, e.g., equal amounts of the respective substances can be used in such substitutions. Thus, the compositions of the invention may also contain (e) vegetable oils and/or (1) esters of the above described carboxylic acids, each in the range of 15 to 60% by weight based on the total weight of the ingredients and (1)- Into such compositions liquid petrolatum can be incorporated in any desired proportion up to about 100% by weight based on the total weight of said ingredients (a) to (f), inclusive. The preferred proportions of the various ingredients are indicated by the above examples.

As further examples of the carboxylic acid esterswhich may be esters of saturated or unsaturated, aliphatic, carbocyclic, or heterocyclic carboxylic acids, and can be used in carrying out this invention-the following are mentioned: dimethyl phthalate, dihexyl sebacate, diglycol oleate, and n-butyl oleate. Esters of acids containing 6-17 carbon atoms in the molecule have been found to give satisfactory results. Dioctyl or dihexyl adipate can also be used.

It has been found that, in order to attain the above stated objects of the invention, the invention must be carried out in the manner described above and defined in the appended claims, whereby the effects of the invention appear to result from a synergistic or co-action of the individual ingredients.

The vegetable oils used in carrying out this invention must be stable, homogeneously miscible with the other ingredients of the composition and cosmetically applicable. This term cosmetically applicable is used in the present application to denote and include products which do not have irritating or other undesired eifects on the human organism, particularly the skin and do not have an undesirable odor.

In order to distribute the compositions embodying this invention on a fibrous carrier, an absorptive fibrous sheet material, such as paper, tissue, towelette or pad consisting of cellulosic or equivalent absorptive fibers, is folded, impregnated with a liquid composition according to the invention and the impregnated piece is then placed in a pouch of plastic material, e.g., cellophane r cellulose acetate, which is then hermetically sealed in conventional manner. The impregnated piece placed in the pouch may be of oblong rectangular shape of, e.g., 4" x 2" before folding. Upon opening the pouch, e.g., by tearing, the towelette placed therein is ready for use. The towelette is then unfolded and wet surfaces of the human skin, e.g., body and face, are rubbed with the towelette immediately after a bath or shower and before drying. The appended drawing diagrammatically illustrates a plastic pouch and an impregnated folded towelette, or pad, placed therein, parts of the pouch and towelette being broken away. The plastic material of the pouch or container must be inert to the bath oils according to the present invention.
